Wireless headphones free you from the tangles of wires and help you listen to music while moving about, and this is especially convenient when the sound source cannot be carried around. However, many of them are based on Bluetooth, which is a lossy medium of transmission, resulting in loss of quality. Rapoo has the H3070 wireless headset based on 2.4 GHz radio frequency (RF), which is less adversely affected by the compression. <br><br>Build And Features<br><br>The H3070 is an on-ear or supra-aural type of headset with an in-built microphone. It doesn't really look anything out of the ordinary at first glance. The cans are rather small, but the 2" diameter is just enough to completely cover the ears. They are entirely black and made of polymer with a rubberised finish on the outside.<br><br>The inside of the earpieces have soft ear-pads covered with soft leather. The 30 mm drivers are placed behind microfiber that should keep off dust and permit almost unobstructed passage of sound. The headband, if we can call it so, is just a stiff strand of metal encased in a transparent and elastic plastic piping. It can be slid in and out of the earpieces to allow for some degree of adjustment of size. The overall design is unappealing and the build quality nothing great. However, it is fairly comfortable to wear.<br><br>Control button and ports are present on the left ear piece and these include a volume control rocker that also acts as the power button when pressed, and a mini-USB port to recharge the internal Lithium battery. An LED present on this ear piece glows red while charging, switching off, or when the battery is low, and it glows green when powered on. A microphone is also present on the left ear piece to be able to use the headset for voice chat.
